How to unset/remove an array in php

Question

Okay, I have an array that is created dependant on what data I receive back from a cURL request. I use a regex expression to grab the data I want and then place it into an array. However the data that is returned differs on every request. The problem I am facing now is in the example below. I seem the have two arrays. One containing 2 strings - which is fine. But they other is a blank/empty array.

Current structure:

array(2) { [0]=> string(1196) "
Please select your address from the list below.
Address 1
Address 2
Address 3
Address 4
Address 5
Address 6
" [1]=> string(1196) "
Different Address 1
Different Address 2
Different Address 3
Different Address 4
Different Address 5
Different Address 6
" } array(0) { }

My question is how would I go around removing/unsetting array(0) { }?

It appears that the additional, empty array is a separate, non-child of your first `array(2)`. Is that the case, or is it a typo? — Irvin Lim, Jun 03 '15 at 17:03

`if(empty($array)){unset($array)}`. why because it is not looking an child array, it is looking a separate array. or if you accidentally put that in a wrong way? — Alive to die - Anant, Jun 03 '15 at 17:05
Which function did you use to generate that layout? Would you please display it via `var_dump` or `print_r`. — Ryan Vincent, Jun 03 '15 at 22:08

Use the php unset function. http://php.net/manual/en/function.unset.php

unset($yourArrayName[0]);

Nope, it doesn't seem to target `array(0) { }` – jakehallas Jun 03 '15 at 21:30
